Katawa Shoujo (Disability Girls) is a romance visual novel covering the life of Hisao following his heart attack and subsequent transfer to a specialist school, along with the romance he finds there. Inspired by a concept sketch by RAITA, Katawa Shoujo is the debut production by Four Leaf Studios, an international project originating on 4chan's /a/ board.

Kenji Setou is Hisao's hallmate and semi-friend at Yamaku Academy. Paranoid to the extreme, Kenji often rambles about a "feminist conspiracy" he believes is taking place in the school, and possibly all of Japan. He trusts no one other than himself, and is always prepared for the worst, even if the worst is irrational.
